tools/ds-identify: ovf identify vmware guest customization.

cloud-init by default sets 'disable_vmware_customization' to True.
So in ds-identify, we will enable the ovf datasource if:

 - virt is vmware
 - 'libdeployPkgPlugin.so' exists as installed by vmware-tools or
   open-vm-tools.
 - disable_vmware_customization is configured to True
